“…Complications after femoral rotation osteotomy have been reported [5,18,22,26]. Although some consider any treatment other than watchful waiting unnecessary even in severe MFT, others believe that increased anteversion may cause osteoarthritis of the hip or knee [1,6,7,12,14,16,23] and that operative correction could prevent this.…”

We reviewed 28 hips in 14 patients with severe bilateral idiopathic medial femoral torsion which had been corrected by intertrochanteric rotation osteotomy using crossed pins for fixation and a hip spica. There were 10 girls and 4 boys with a mean age of 7 years and 9 months. All had functional and cosmetic disability before operation. The average follow up was for 3 years and 9 months. Full correction was achieved in 27 hips. In one partial avascular necrosis of the femoral head occurred one year after operation and was treated by an acetabular augmentation procedure with a satisfactory outcome.

“…However, the cause of primary osteoarthritis is multifactorial and is not solely dependent on the altered geometry of excessive anteversion [6]. A study of radiographs of the hips of 220 consecutive cadavers has not shown a significant difference between the degree of anteversion in osteoarthriftc and normal hips [24].…”

“…These include mainly the lower limb alignment and knee adduction moment forces increasing the load across the articular cartilage and/or changing the material properties [14][15][16][17][18][19]. There are several reports pointing out the aetio-pathogenetic relation between the osteoarthritis of the hip, knee and lower extremity torsion [3][4][5][6][7][8]10]. In addition, after working for several years at a musculoskeletal radiology or orthopaedic outpatient clinic, it is not uncommon to observe hip and knee osteoarthritis simultaneously at the same extremity of the patient.…”

Purpose Biomechanic factors play a role in the pathogenesis of knee osteoarthritis. The aim of the study was to find out whether there is a relation between femoral, acetabular anteversions, anterior, posterior acetabular coverages and primary osteoarthritis of the knee. Methods Thirty patients with primary osteoarthritis of the knee and 29 control subjects were enrolled into the study. Femoral anteversion, acetabular anteversion, McKibbin's instability index, anterior acetabular sector and posterior acetabular sector angles were measured using tomographic scanograms. Results There was no difference between groups for each parameter (P [ 0.05). Conclusion This study did not show any relationship between the axial plane changes in the hip joint and primary knee osteoarthritis.

“…The femoral collodiaphyseal angle becomes abnormal as the upper portion of the femur is over-anteverted. Halpern et al identified over-anteversion of femoral heads as the leading cause of hip pain in patients [8]. Loading increases the pressure on the cartilage by up to 250%.…”

Objective: This study aims to compare the pelvic biomechanics of patients who underwent Salter innominate osteotomy (SIO) for one hip and Pemberton pericapsular osteotomy (PPO) for the other hip. Materials and Methods:Fifty-seven of 126 patients who received a one-stage procedure involving SIO for one hip and PPO for the other hip were included in this series. Preoperative x-rays, archived reports and patient recall were obtained and retrospectively analyzed for these 57 patients. Pelvic biomechanics of the two osteotomy techniques were compared on x-rays and computerized tomography imaging. Results:Based on x-rays, three hips with SIO and 1 hip with PPO had changes that could reflect unstable pelvic biomechanics. SIO caused an average lower limb discrepancy of 0.47 cm in all patients. Positive results were found in 5 patients at their most recent clinical examination. Conclusion:PPO affects the biomechanics of the pelvis much less than SIO. PPO demonstrated ideal biomechanical results compared with SIO, with fewer changes to the pelvic ring and the hip joints.
